Ultrasonic heat meter with digital output RS485 or MBUS


Ultrasonic apartment heat meter "Pulsar" with digital output is a compact device designed for metering the consumption of thermal energy in an apartment, private house, small office or retail space. Installed in a pipeline that provides heat supply to the facility. Designed for visual data reading. The device is equipped with a digital RS485 interface, which allows data transmission to a control center located at a distance. This allows you to read data without direct access to the device and even without visiting the apartment in which it is located. The warranty period is 6 years.
